P key needs new nipple; contact works. How to replace?
I have a PB here with a P key not working. I've replaced the scissor mechanism but the problem is that the springy rubber nipple is damaged. When I press on the contact underneath, it does type Ps with apparent contentment.
I found a source at http://www.irithm.com/Mac.key.replacemen...
with pretty good instructions, but, while they can provide the nipple, they don't say how to install it. It appears to be glued onto the keyboard base. (ifixit only sells complete keyboards.)
